Launch of the PHAGO project to explore a new approach for patients suffering from Alzheimer’s disease

11 January 2017

On 1st November 2016 the Innovative Medicines Initiative (IMI) together with an association of industrial partners came together to support PHAGO, an innovative research project devoted to the development of immunomodulatory therapies for Alzheimer’s disease (AD).

Dr Jennifer Pocock and Professor John Hardy (UCL Institute of Neurology) have been awarded £733,000 together with matched industrial funding (in kind) for 5 years.

"University College London Institute of Neurology is proud to be part of this consortium.  We look forward to working with all our other partners to push forward this exciting area of research for dementia, and particularly Alzheimer’s disease."  Dr Jennifer Pocock together with Co-PI Professor John Hardy, UCL Institute of Neurology

Today, over 46 million people live with dementia worldwide and this number is estimated to increase to 131.5 million by 2050. Affected patients suffer from memory loss and progressive dementia. Although current treatments can slightly delay some mental symptoms, there is currently no cure. The burden on caregivers who are often family members is huge. With an estimated 160 billion Euros of costs of care annually in Europe alone, this translates into a high socio-economic burden.

It has been known for many years that specialized types of immune cells accumulate around amyloid plaques (one of the pathological hallmarks of Alzheimer’s disease) in the brains of patients and show a dysfunctional activation profile. Recent systems biology approaches based on genome-wide association studies and brain gene expression profiling identified the innate immune receptor genes TREM2 and CD33/SIGLEC3 as disease relevant players in Alzheimer’s disease. These findings present novel and attractive targets for treatment. However a complete understanding of their exact role and underlying cellular mechanisms is still unclear. PHAGO aims to fill this knowledge gap and provide tools and assays for targeting these immune receptors to pave the way for the development of drugs that delay the progression of Alzheimer’s disease.

“We are seeking to understand the immune response in Alzheimer’s disease. To this aim, we will analyse the function of both immune receptors in more detail and will set up tools and assay systems to establish pharmaceutical interventions”. Professor Harald Neumann, University Hospital of Bonn and PHAGO project coordinator

The ambition of PHAGO is to improve patient outcomes through better understanding of the biology of TREM2 and CD33/SIGLEC3 and their biological networks and pathways, and develop therapies aimed at modulating the immune dysfunction in Alzheimer’s disease. To achieve this, PHAGO brings together experts from industry and academia in a powerful collaboration.

“The research project's value is its interdisciplinary approach focused on two relevant immune cell receptors suspected to be involved in Alzheimer’s disease. By bringing together scientific knowledge of leading European experts from different technical areas on TREM2 and CD33, we will be able to establish and exploit innovative tools on TREM2/CD33 suitable for pharmaceutical and industrial application. Over time, our ambition is that these contribute to the development of drugs for the treatment of Alzheimer’s disease.”  Dr. Andreas Ebneth, project leader at Janssen Pharmaceutica NV.
“I see great potential for this project to develop a way to intervene pharmacologically in the TREM2 and CD33 pathways for the treatment of this devastating disease”. Dr. Laurent Pradier, project co-leader at Sanofi.

PHAGO is supported by the IMI with 8.8 million Euros and by further industrial partners with 9.1 million Euros. The project runs over five years and will end on 31st October 2021.

The parties involved

Under the name PHAGO, the new research consortium unites pharmaceutical companies, small biotechnology enterprises and public research organisations from across Europe. Pharmaceutical partners are: Janssen Pharmaceutical NV (Belgium); Sanofi (France); Eli Lilly, AstraZeneca AB (UK); Lundbeck (Denmark); AbbVie (Germany); Roche (Switzerland) and Orion Pharma (Finland). Biotechnology related enterprise members are: Axxam SpA (Italy), Life & Brain GmbH (Germany) and ARTTIC (France). Completing the consortium are academic institutions from across Europe: University Hospital of Bonn, German Center for Neurodegenerative Diseases, Charité – Universitätsmedizin Berlin and Fraunhofer Institute SCAI (Germany); King’s College London, University College London and University of Cambridge (UK); and University of Gothenburg (Sweden).
